dvlopt.mbus

Thin clojure wrapper around JMbus for communicating with Meter-Bus slave devices.

Supports a (very) wide variety of platforms.

Installation

This library needs jRxTx for using serial ports. For instructions, refer to Clotty, our own clojure wrapper.

Then, simply add the following dependency to your project :

Usage

Read the full API.

In short :

(require '[dvlopt.mbus       :as mbus]
         '[dvlopt.mbus.wired :as mbus.wired])


;; Open a connection on the serial port.

(def connection
     (::mbus.wired/connection (mbus.wired/open-serial "/dev/ttyUSB0"
                                                      {::mbus/timeout   1000
                                                       ::mbus/baud-rate 2400})))


;; Request user data from slave 0

(mbus.wired/req-ud2 connection
                    0)

Status

If you need wireless M-Bus, you need to interop with JMbus. We will write a wrapper as soon as we have the relevant hardware to test it.
